If you're that concerned about it, go grab a raspberry pi and get cracking on your own compute environment. You don't actually need all the OS stuff as you keep arguing, so go make it so.
Of course you're ignoring the fact that linux is open source, so you can go make the OS do what you want it to - that's one path you could take.
Or you could just write code for the rpi and build up all that stuff yourself, no problem.
The only person stopping you from doing this is yourself.... go do it and show us the "no-os" way.
I think you read my previous comment as an argument against what I was replying to. I was actually agreeing with them and acknowledging they have a great point.
